Notice that the approximation is much closer for larger $x$, as $w(x) = \exp(\pi x)$ gives more weight to the error introduced there. We can take advantage of that aspect in our calculation of Harmonic Oscillator wavefunctions. Theses polynomyals are Chebyshev polynomials, Hermite polynomials, Generalized Laguerre polynomials and Legendre polynomials. I designed this web site and wrote all the mathematical theory, online exercises, formulas and calculators. It is this minimization property that is responsible for some of the power of orthogonal polynomials. For each of these examples, there are readily derived recurrence relations which allow fast computation of the polynomials, and Chebfun exploits these. Such a measure is represented by a non-decreasing function (), satisfying the periodicity condition ( 2 + 2) ( 1 + 2 ) = ( 2) ( 1) for .
